1. In a patient with chronic obstructive pulmonary disease (COPD), which of the following interventions is most important?

• A. Encouraging the patient to stop smoking.
• B. Administering bronchodilators.
• C. Monitoring oxygen saturation.
• D. Providing nutritional support.

Correct answer: C

Rationale: Monitoring oxygen saturation is the most important intervention in a patient with COPD because it helps assess the adequacy of oxygenation. In COPD, patients often have compromised lung function, leading to decreased oxygen levels in the blood. Monitoring oxygen saturation allows healthcare providers to promptly identify and address any potential hypoxemia, which is vital in managing COPD exacerbations. While encouraging the patient to stop smoking (Choice A) is critical for long-term management, monitoring oxygen saturation takes precedence in the immediate care of a COPD patient. Administering bronchodilators (Choice B) and providing nutritional support (Choice D) are important aspects of managing COPD but are secondary to monitoring oxygen saturation, which directly impacts the patient's oxygenation status.

2. The nurse is preparing to administer trimethoprim-sulfamethoxazole (TMP-SMX) to a patient who is being treated for a urinary tract infection. The nurse learns that the patient has type 2 diabetes mellitus and takes a sulfonylurea oral antidiabetic drug. The nurse will monitor this patient closely for which effect?

• A. Headaches
• B. Hypertension
• C. Hypoglycemia
• D. Superinfection

Correct answer: C

Rationale: When a patient takes oral antidiabetic agents (sulfonylurea) along with sulfonamides like trimethoprim-sulfamethoxazole, it can lead to an increased hypoglycemic effect. Therefore, the nurse should monitor the patient closely for hypoglycemia. Headaches, hypertension, and superinfection are not typically associated with the interaction between sulfonamides and sulfonylureas. Examples of antidiabetic sulfonylurea medications include glipizide, glimepiride, glyburide, tolazamide, and tolbutamide.

3. A client with a diagnosis of hypothermia is being admitted to the hospital by a nurse. Which of the following signs does the nurse anticipate that this client will exhibit?

• A. Increased heart rate and increased blood pressure
• B. Increased heart rate and decreased blood pressure
• C. Decreased heart rate and increased blood pressure
• D. Decreased heart rate and decreased blood pressure

Correct answer: D

Rationale: Hypothermia decreases the heart rate and blood pressure due to reduced metabolic needs of the body. With lower metabolic demands, the heart's workload decreases, leading to reductions in both heart rate and blood pressure. Choices A, B, and C are incorrect because hypothermia typically results in a decrease in heart rate and blood pressure, not an increase.

4. A client in the emergency department is severely dehydrated and is prescribed 3 L of intravenous fluid over 6 hours. At what rate (mL/hr) should the nurse set the intravenous pump to infuse the fluids? (Record your answer using a whole number.)

• A. 500 mL/hr
• B. 400 mL/hr
• C. 550 mL/hr
• D. 600 mL/hr

Correct answer: A

Rationale: To calculate the rate of the intravenous pump, divide the total volume of fluid (3 L = 3000 mL) by the total time in hours (6 hours), which equals 500 mL/hr. The correct answer is A. Choice B (400 mL/hr) is incorrect as it would result in a slower infusion rate. Choice C (550 mL/hr) and Choice D (600 mL/hr) are incorrect as they would result in a faster infusion rate, exceeding the prescribed amount of fluid to be infused over 6 hours.

5. Why is lactated Ringer’s solution given to a patient experiencing vomiting and diarrhea?

• A. To increase interstitial and intracellular hydration
• B. To maintain plasma volume over time
• C. To pull water from the interstitial space into the extracellular fluid
• D. To replace water and electrolytes

Correct answer: D

Rationale: Lactated Ringer’s solution is an isotonic solution commonly used to replace water and electrolytes lost due to conditions like vomiting and diarrhea. It helps to restore fluid balance by replacing the lost volume and electrolytes. Option A is incorrect because hypotonic fluids, not lactated Ringer’s solution, increase interstitial and intracellular hydration. Option B is incorrect as colloidal solutions, not lactated Ringer’s solution, are used to maintain plasma volume over time. Option C is incorrect as hypertonic solutions, not lactated Ringer’s solution, pull water from the interstitial space into the extracellular fluid.
